To reproduce the orbits and masses of the terrestrial planets (analogs) of the solar system, most studies scrutinize simulations for success as a batch. However, there is insufficient discussion in ...

A study simulating the final stages of terrestrial planet formation shows that ‘hit-and-run’ encounters play a significant role in the acquisition of water by large protoplanets, like those that grew ...

The solar system originated from a collapsing cloud of gas and dust approximately 4.5 billion years ago, with the Sun forming in the central region through nuclear fusion and the planets condensing ...

Astronomers have confirmed the discovery of only the third known interstellar object everobserved passing through our Solar ...

The solar system is 4.54 billion years old, based on rock dating. Gas giants (Jupiter and Saturn) likely formed first. Ice giants (Uranus and Neptune) probably formed next. Rocky planets formed last, ...

A large international team led by astronomers at the Trottier Institute for Research on Exoplanets at Université de Montréal (UdeM) today announced in the journal Nature the discovery of a new ...

3I/ATLAS has now made its closest approach to the sun and Earth and is now heading back out toward the outer solar system. On ...

The Cassiopeia solar project aims to use the sunlight collected by a space satellite for terrestrial energy needs. The electricity generated would be converted to radio frequency microwave radiation ...
